TRANSMISSION MECHANISM.

Specification of Letters Patent.

Patented Slept. 2d, 1914.

To all whom it may concern Be it known that I, Nonnnnro MARTINEZ, a citizen of Mexico, residing at Cotulla, in the county of Lasalle and State of Texas, have invented new and useful Improvements in Transmission Mechanism, of which the following is aspecification.

The primary object of the invention is the provision of a device of this character wherein reciprocatory motion is converted into rotary. motion with multiplied power, thus ()ther objects will be in part obvious and in part hereinafter pointed out.

lfhe invention accordingly consists in the construction, combination of elements and arrangement or" parts which will be eXemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the appended claims.

In toe drawings:-Figure 1 is a side elevation of a device constructed in accordance with the invention, showing its counter bal ance wheel partly broken away. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical longitudinal sectional view thereof on the line 3-3 of Fig. 2. Fig. 1 is a similar view on the line 4:4c of Fig. 2. Fig. dis a view similar to Fig. 2, with the slide and rollers removed. Fig. 6 is a sectional view on the line G-6 of Fig. 3.

Similar reference characters. indicate corresponding parts throughout the several views in the drawings.

lleferring to the drawings in detail, the device comprises a base A formed with a rest bed B on which are fixed near opposite ends thereof spaced vertical uprights 10 formed with bearings 11 inwhic-h are lour-- naled' transversely disposed shafts 12 and 13 respectively, each carrying at one end a fly wheel let, While mounted on its opposite end is a belt pulley 15 over which is adapted to be trained a driven belt for the transmission of power from the device to machinery or the like.

Arranged on the bed. B between the shafts 12 and '18 are bearing rollers 16, each being formed with a peripheral groove 17, and in these grooves engage guide ribs 18 formed on and depending from the under face of a slide or movable table 19 having mounted therein spacedcfrom opposite ends vertical pins .20 on which are removably fitted weight blocks 21, the rollers 16 being movable longitudinally of the bed B for a limited distance, while pivoted to a bearing 22 at a point intermediate the ends of the bed B is a. rocking lever 23, the same being piv oted at 2 1 to bearing lugs 25 formedon'the slide or table- 19, and this leve extends up wardly through the slot 26 in the slide or table and has pivotally connected to its upper end a throw rod 27 so that driving energy can be imparted to the lever 23 for the rocking thereof to impart movement to the slide or table 19, which in turn rotates the roller 16 on the bed B for a purpose presently described.

The shafts 12 and 13 are formed with pairs of oppositely extending eranks28 and 29 respectively, to which are loosely connected links 30, the same being also pivoted to walking beams 31 and 32 respectively, which are supported upon a pivot 33 common to all of the beams or levers, and mounted in the base. The bed B of the base A is formed with slots 34: through which work the links 30 and the beams or levers 31 and 32, the latter being titted with tread shoes or blocks 35 and 36 respectively, against the beveled edges 3? of which. act the rollers 16 so that the levers 31 and 32 will become active for the rotation of the shafts 12 and 13. As each roller 16 travels upon the beveled edge 37 of either shoe or block 35 or 36 .it causes the downward movement of the lever or beam carrying the same, and in this manner rotary movement is inlpart-ed to each shall; so that reoiprocatory ill . table 19, while the arm 39 serves to limit the throw thereof during the activity of the device.

It will be noted that the backward and forward movements of the roller 16 serve to move the arms or levers 31 and 32 in their order, which causes a continuous rotation to the shafts 12 and 18 and from which similar motion will be imparted to machincry or the like for driving the same. On converting the reciprocatory movement into rotary motion it will be noted that by reason of the particular arrangement the power thereof is multiplied to give maximum force .to the device without increasing the driving energy.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. A device of the class described comprising a support, a plurality of swinging levers, a pivot on the support and common to the levers, crank shafts journaled above the support, links loosely connected to the cranks and pivoted to the levers, beveled tread members on the levers, and roller means movable on the support for working against the tread members to displace the levers.

2. A device of the class described com prising a support, a pluralityof swinging levers, a pivot on the support and common to the levers, crank shafts journaled above the support, links loosely connected to the cranks and pivoted to the levers, beveled tread members on the lovers, roller means movable on the support for working against the tread members to displace the levers, and means for setting the roller members in motion.

3. A device of the class described comprising a support, a plurality of swinging levers, a pivot on the support and common to the levers, crank shafts journaled above the support, links loosely connected to the cranks and pivoted to the levers, beveled tread members on the levers, roller means movable on the support for working against,

the tread members to displace the levers,

means for setting the roller members in motion, and means for limiting the movement of the last-named means.

4:.
